[sqlite] Virtual tables

[Matthew Jones]

Is there any straight forward way I could use SQLite3 with virtual 
tables. By that I mean SQLite contains all the table and index 
definitions but none of the data - actually it will contain the data for 
some tables but not others. I only need to query access to the tables so 
I need to intercept the fetching of data from these virtual tables & 
indices. From what I have read in the architecture, it seems like I want 
to intercept the btree implementation for these virtual tables but that 
doesn't mean it has to be done that way.

Thanks
